AW Sge : negative superhump derivative

 We have receieved further observations from Josch
Hambsch and Bart Staels. With these data, the refined 
superhump period is 0.074950 (16) d.
 The O-C diagram implies that Pdot is negative. It is
still uncertain whether stage A exist or not since
it is unclear whether the earlest stage is stage A or
a part of stage B with only O-C diagram.

 Further observations are encouraged!
